Description

Technical Field

[0001] The utility model relates to the technical field of ammonia treatment, and more specifically to a spray tower for treating ammonia. Background Art

[0002] In the process of breeding black soldier flies, a spray tower is usually equipped to remove ammonia from the exhaust gas. However, over time, a large amount of ammonia merges with water to form ammonia-containing wastewater, and its treatment process is both complicated and cumbersome. Traditional methods for treating waste ammonia water often convert it into non-volatile substances or remove ammonia, but the above process has problems such as high treatment costs and high environmental pollution risks.

[0003] The current method of treating ammonia is to use aqueous solution absorption method, which is to directly input ammonia into the water, then let air float to the surface with the water depth, and then discharge the gas. However, in the above treatment process, ammonia is discharged from the same place, causing the nearby water to absorb ammonia to become saturated, resulting in residual ammonia. After the residual ammonia is discharged, it will pollute the air environment. Utility Model Content
